Hi, i want to make a simple event in C++ that can be used in a blueprint like the “Mouse X” event that have the “Axis Value” parameter.
I work in version 4.6.1

I’ve tried many variations of UFUNCTION(BlueprintImplementableEvent)
or UFUNCTION(BlueprintNativeEvent)
but non if my tryouts have worked - The event is not visible in my blueprint
If i do something like that, without a parameter, it works and i can find it in the blueprint.
UFUNCTION(BlueprintImplementableEvent, Category = "GlobalEvents")
void SpawnLevelActor();

If i change it to something like that it is not visible in the blueprint anymore.
I want it to be a real event node, not a function.
UFUNCTION(BlueprintImplementableEvent, Category = "GlobalEvents")
void SpawnLevelActor(FString &ClassName);
My goal is generally:
I want firing an event from c++ and passing some parameters to it - In a blueprint i want do something when this event has been fired, include the use of the parameters that i’ve passed from c++.
Maybe my general understanding of how i should make it is wrong - Any help would be much appreciated.
Second time i feel dumb Thx, it works exactly as it should. I everytime came across such simple mistakes - Have you maybe a good documentiation where i can find such things with example code. I came from unity and they have a very good documentation with many example code, for unreal i didn’t found anything similar except the API documentation, without example code.
Thx. I also already found this platform, i guess i need a bit more time to know where to find things.
